ADJUSTABLE HOSE-COUPLING BAND.

SPECIFICATION forming part of Letters Patent No. 519,312, dated May 8, 189%. Application filed April 26, 1 892. Serial No. 430,804. (No model.)

To all whom it may concern:

Be it known that I, EVAN R. ARTHUR, a citizen of the United States, residing in Portage, in the county of Columbia and State of Wisconsin, have invented certain new and useful Improvements in Hose-Bands; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The main objects of my invention are to provide a hose coupling band which may be readily fitted to any size of hose, and to prevent the material of the hose from being forced outwardly into the opening between the lugs or ears employed to compress and hold the band upon the hose, or between the edges of the tongue provided to close said opening and the sides of the recess which said tongue enters.

To this end my invention consists essentially of a band of metal either cast or struck up, formed in two parts so made as to interlook at different lengths or to be interchangeable one with another without regard to length, and so made that the two parts will be kept in line with each other when applied to the hose; of a tongue at one end of the band of sufficient strength to enable it to be forced underneath the opposite end of the hand without buckling and of sufficient width to prevent the material of the hose from being forced outwardly between the ears or lugs or between the edges of the tongue and the sides of the recess which it enters when the i band is being applied to the hose; and of certain other peculiarities of construction and arrangement hereinafter particularly described and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a perspective view of an adjustable hose band embodying my improvements, the component parts of the band being separated at one end and-partially interlocked at the other. Fig. 2 is a medial longitudinal section of the band, the component parts being interlocked and connected as when applied to hose. Fig. 3 is a plan view of a portion of one of the component parts, and Fig.

at a side elevation of a portion of the, other part of the band showing the interlocking connection by which the length of the band may be varied; Fig. 5 is a cross section of the band at a point where the component sections overlap, as on the line 5, 5, Fig. 2. Fig. 6 is a similar section on the line 6, 6, Fig. 9, showing a modified form of the component parts of the band. Fig. 7 is a perspective View showing the inner side of the overlapping end of the band. Fig. 8 is a cross section on the line 8, 8, Fig. 2, showing one of the lugs and the seat with whichit is provided for holding the nut on the clamping screw from turning. Fig. 9 is an edge elevation of a portion of a modified form of hose band to which my improvements are applicable, and Figs. 10 and 11 are details in perspective of opposite ends of the band showing the device for fastening and holding it upon the hose.

Referring to Figs. 1 to 5 inclusive, A and B represent-the two component parts or sections of the band,which are formed with longitudinal grooves or recesses on their inner sides, the inwardly projecting edges or ribs on either side thereof serving incidentally to compress the material of the hose into the grooves or recesses in the shanks of the hose couplings and thereby hold the same securely thereon. The underlying part or section A of the band is formed on the outside with a corresponding rib or projection which fits into the internal groove or recess in the overlapping part or section, as shown in Figs. 2 and 5, and thereby holds the component parts of the band in line with each other when they are assembled and are being applied to the hose. One part A, of the band is formed in the direction of its length with a series of holes a a, and the other part B, with lugs b b at or near one end thereof, adapted to be inserted in any of said holes and thus adjustably lock the parts together at one end. lug I) being provided simply for the purpose of additional strength, may be omitted.
